I have a Samsung Galaxy. Last night I put it on charge. This morning it still said charging. So I unplugged it. It was just showing the Samsung fading in and out emblem, then changed to the galaxy symbol with all moving lines.(if you have one you'll know what I mean) I couldn't get any sound from it or any life, these symbols kept on interchanging for hours. I took the battery out and replaced it again. Still no change. Eventually everything vanished from screen. Can't get any life out of it at all. Can anyone help please.
